The founding of the Carnegie Institute’s Department of Embryology in 1913, alongside its systematization of embryo staging, contributed to the mechanization of developmental stages of embryo growth in the early 20th century. For a brief period in the middle of the century, attention to the detailed interrelation between embryo development and time made pre-existing ideas about pregnancy ends less determinative of ideas about that developmental course. However, the turn to the genetic scale led to the disappearance of this attention, replaced by a sense of biological life as seamlessly scripted. This study examines the history of what I refer to as temporal attention: attention to the live, unfolding potentialities within vital matter. The reintroduction of temporal attention to discussions of development allows us to more fully consider non-human vitality and the experiences of beings that house or otherwise intimately intersect with that vital tissue, regardless of outcomes.

The placenta has played an important role in feminist theories of subjectivity; however, the placenta of feminist theory has been the fully functional placenta of what is considered a successful full-term pregnancy. Pregnancy loss, a topic that has been generally overlooked within feminist scholarship, is absent from feminist theories of the placenta. This article uses early placental development, particularly development that takes place before the placenta becomes fully functional as an organ for hormone production and interchange, as a space through which to consider theorising subjectivity, reproduction and relation through pregnancy loss. In so doing, I argue that turning our attention to the placenta’s early development, regardless of outcomes, allows us to reimagine the role of process for feminist theories of subjectivity while also making room for a wider array of pregnancy outcomes, reinvigorating our ability to think about relations and models of hospitality that do not end as we might imagine.
